The lamp bulb is a ceramic bulb, the conductive support is provided with a getter, and the ceramic electric arc tube has an ellipsoid shape, a ball shape, a cylindrical shape or a flame shape. Compared to the prior art, the ceramic xenon lamp is advantageous in that performance is stable, light decay is small, service life is long, energy saving effect is achieved, aberration is little, color temperature drift is little, the application scope is wide, and popularization is easy.
Description
Technical field
The utility model relates to a kind of lighting, specifically a kind of ceramic xenon lamp of simple in structure, low energy.
Background technology
The HID xenon lamp is to excite arc discharge and luminous a kind of high efficiency light source by xenon gas under the high voltage ionized state.Present HID xenon lamp all is electric arc tube with the transparency silica glass.Though quartz glass has very high thermal stability, can stand violent temperature difference cataclysm.But during because of xenon lamp work, temperature is up to nearly thousand degree (maximum temperature of quartz material can not above 1000 ℃) in the electric arc tube, air pressure is up to the dozens of atmospheric pressure, so, requirement to electric arc tube is quite harsh, with this understanding, the crystallization temperature characteristic of quartz material and pyrochemical unsteadiness, make the working temperature of the quartz material in the quartzy xenon lamp limit the interior effective steam pressure of electric arc tube, light efficiency and color rendering are also therefore limited, so produced relatively poor relatively lumen depreciation, life period photochromic can change etc. shortcoming.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of simple in structure, ceramic xenon lamp that useful life is long, energy-conservation is provided.
The technical solution of the utility model realizes in the following manner, this a kind of ceramic xenon lamp, its structure comprises cell-shell, connects the lamp socket of cell-shell, described cell-shell inside is provided with conducting bracket, the metal electrode that is connected with conducting bracket and is arranged on ceramic arc tube between the metal electrode, described cell-shell is ceramic cell-shell, conducting bracket is provided with getter, and above-mentioned ceramic arc tube is ellipsoid shape, spherical shape, cylindric or flamboyancy.
As preferably, also be provided with U-shaped stress button on the above-mentioned metal electrode.
Further, the inwall of described ceramic arc tube is provided with fluorescence coating, and this fluorescence coating is the fluorescence coating that is filled with gradual change fluorescent material.So just can realize the true effect of light color gradual change, more help the light efficiency of whole lamp system to promote more than 40%.
Further, the bottom of described lamp socket is provided with the ceramic insulation sheet.This ceramic insulation sheet can guarantee that whole lamp body is more safe and reliable.
The beneficial effect that the utility model compared with prior art produces is:
A kind of ceramic xenon lamp of the present utility model has simple in structure, easy to use, characteristics such as be skillfully constructed, cell-shell and electric arc tube all adopt pottery to make, thermal stability and chemical stability are very high, chemical reaction does not take place with the material that charges into electric arc tube, there is not leakage problems again, therefore lamp behaviour is stable, light decay is littler, life-span is longer, low energy, aberration is few, the colour temperature drift is little, the scope of application is extensive, can be widely used in road, the tunnel, the square, the station, port and pier, the airport, the gas station, indoor and outdoors such as market underground parking factory and modernized factory building height colour developing illumination place has effects such as the illumination of raising quality and minimizing traffic accident.

Mark in the accompanying drawing is represented respectively:
1, cell-shell, 2, conducting bracket, 3, fluorescence coating, 4, ceramic arc tube, 5, the stress button, 6, lamp socket, 7, the ceramic insulation sheet, 8, metal electrode, 9, getter.
Embodiment
Below in conjunction with accompanying drawing a kind of ceramic xenon lamp of the present utility model is done following detailed description the in detail.
As accompanying drawing 1, Fig. 2, shown in Figure 3, this a kind of ceramic xenon lamp, its structure comprises cell-shell 1, connects the lamp socket of cell-shell 1, described cell-shell 1 inside is provided with conducting bracket 2, the metal electrode 8 that is connected with conducting bracket 2 and is arranged on ceramic arc tube 4 between the metal electrode 8, described cell-shell 1 is ceramic cell-shell, conducting bracket 2 is provided with getter 9, above-mentioned ceramic arc tube 4 is ellipsoid shape, spherical shape, cylindric or flamboyancy, the inwall of ceramic arc tube 4 is provided with fluorescence coating 3, and described cell-shell 1 is ceramic cell-shell.
Also be provided with U-shaped stress button 5 on the above-mentioned metal electrode 8.
The inwall of described ceramic arc tube 4 is provided with fluorescence coating 3, and this fluorescence coating 3 is for being filled with the fluorescence coating of gradual change fluorescent material.The bottom of described lamp socket 6 is provided with ceramic insulation sheet 7.
Described ceramic arc tube 4, cell-shell 1 all adopt polycrystalline alumina ceramic to make.This pottery is a kind of trnaslucent materials, and his light transmittance surpasses quartz glass (93%) up to 98% in fact, but because straight-line luminous transmittance is no more than 30%, understands so just become semi-transparent.This ceramic material can bear than the high high temperature more than 200 ℃ of quartz, making behind the electric arc tube natural running temperature can be up to 1200 ℃, and in addition its thermal conductivity is higher, and the electric arc tube self-temperature distributes comparatively even, even cold junction also more than 900 ℃, therefore charges into xenon wherein
Gas can fully evaporate.Adopt this ceramic material not only can overcome the deficiency that quartzy xenon lamp exists, and integrate the advantage of high-pressure sodium lamp and quartzy xenon lamp: luminous efficiency improves 15%～20% than quartzy xenon lamp, do not consider the mesopic vision relation, the light efficiency of the following specification of 150W is higher than the xenon lamp with power; Color rendering improves 8%～10% than quartzy xenon lamp; The light maintenance is better, and it is more stable to start requirement, and the life-span is longer; Aberration is few, and the colour temperature drift is little.
Because lamp socket 6 bottom design have ceramic insulation sheet 7; can better play a protective role; further; lamp socket 6 all can be designed to pottery makes; simultaneously lamp socket is made into non-threaded connection shape; be designed to buckle and connect shape, so just can avoid the trouble that is threaded, can realize fixing of xenon lamp more fast.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
